ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 243,791, dated July 5,1881.

Application filed February 3, 1881. (No model.)

To all whom it may concern:

Be itknown that I, EMANUEL RABER, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Elevators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 is an end View of the elevator. Fig. 2 is a longitudinalsection on line 2 2, Fig. 1. Fig. 3 shows a modified form of trigger.

A represent a beam on which the elevator is.

mounted. The beam is preferably arranged in the upper part of the barn.

B B are ribs which rest upon the upper side of the beam.

C O are downwardly-extending side pieces attached to the ribs B andarranged one on each side of the beam. Friction-rollers may besubstituted for the ribs 13.

If necessary the upper parts of the frame may be joined by suitablegirts, as indicated by dotted lines.

D is a bottom piece connecting thelower edges of the parts 0.

E is a pulley near one end of the bottom piece, D. r

F is a pulley mounted in a block, G G, the latter having aneye or loopat the lower end for attaching the load, and having at the upper end aneye for the insertion of a hook.

H is a rope attached at one end to the carriage and running under pulleyF and over pulley E to the point where is applied the power whichelevates the material.

I I is a hook mounted in the carriage, between the side pieces, 0 C. Itis held in place by pins 0 and O, the hook being provided with a slot,11, for the pin 0, and with a slot, '5' '5 for the pin 0'. The slot t isconcentric with the lower part of the slot z, and the slots i i arenotches or recesses in the upper edge of the hook, near its heel end.

J is a stop or trigger mounted in beam A. It may be supported either bya stationary pin engaging with the trigger by means of a slot in thelatter or supported by a pin fastened to the trigger and arranged torest upon the top of the beam, as shown in dotted lines, Fig. 2.

ger J. The upward movement of these parts will be stopped when the pin 0is in the position indicated by the dotted lines, Fig. 2. If theelevator-carriage be then moved in the direction of the arrow y, Fig. 2,the radial wall of notch i will engage with the side j of trigger J, andthehook II will be rotated sufficiently to cause the part I to enter theeye 9 of the pulley-block. After said point has entered said eye thecorner i near the heel of the hook, reaches the bottom of the triggerand passes the same, and the pulley-block and the load are thensuspended upon the hook I I. The load is carried in the direction of thearrow y to the desired point, and is then released fromthe'fork or otherholder. (Not shown.) After the load is dropped the carriage is returned.to the position shown in Fig. 2. While returning to said position theradial wall of the notch t strikes the opposite side, j, of the triggerJ, and the hook is turned into the position shown in Said figure. Theturning up of the hook releases the pulley-block, which is lowered foranother load. \Vhen the trigger and carriage are in the positions shownthe carriage is prevented from being moved in the direction of arrow yuntil the hook I I and the trigger J are elevated by the pulley-block.

The trigger may be made in the shape shown in Fig. 3 and pivoted in acorresponding slot in the beam. In many respects a trigger of the latterconstruction is preferable to the one IOC 13 i 11 and of a hook havingmovable pins atbination with the studs 0 O, substantially as tachedthereto.
